Hot water systems in Dartnall
Across Dartnall, more households are rethinking their old gas and electric hot water system and switching to smarter options like a heat pump hot water system, solar hot water system or modern electric hot water system. With most of the 193 occupied dwellings being separate houses and an average household size of 2.6 people, hot water demand is steady all year round – and so are the power bills if your unit is outdated.
Dartnall is actually very well suited to efficient hot water. The local weather station records an average annual solar exposure of about 17.5 MJ/m² per day, which is roughly 4.9 kWh of solar energy hitting each square metre of roof every day. That level of sunshine helps a solar hot water heating system and heat pump hot water installation perform reliably, especially for family homes and the many owner‑occupied properties (over half are owned outright). For households on a median weekly income of around $1,307, shifting from an older gas or resistive electric unit to an energy efficient hot water system can free up real money each quarter.
In 6320, most homes are three‑ and four‑bedroom places, so a correctly sized hot water installation is important. A typical family here might look at a 250–315 litre heat pump hot water system or a roof‑mounted solar hot water installation with a 250–300 litre solar hot water tank replacement. Brands like Rheem, Rinnai, Sanden and Thermann are common choices, offering everything from rheem solar hot water and rheem heat pump hot water to rinnai solar hot water and premium sanden heat pump units that are often rated among the best heat pump hot water system options in Australia. For many, the decision comes down to heat pump vs solar hot water, or solar hot water vs electric hot water backed by rooftop solar.
To give a feel for savings, here are typical annual bill reductions Dartnall households might see when upgrading:
• Old electric hot water to heat pump: $400–$800 per year • Gas storage to heat pump: $300–$600 per year • Gas storage to solar hot water system: $250–$550 per year • Old electric to modern electric hot water installation with rooftop solar: $250–$500 per year
Local data shows this is not just theory. There have already been 74 efficient hot water systems installed in the Dartnall postcode, combining heat pump and solar hot water systems. Installations climbed through the 2000s, peaking around 2009 and 2011, with solid years again in 2014 and 2019. More recent heat pump hot water installation numbers are smaller but reflect a steady base of homeowners interested in electrification, lower running costs and the most efficient hot water system they can afford. As more residents add rooftop solar, pairing it with an electric or solar hot water system is an obvious next step.
When it comes to hot water repair, hot water system price and ongoing running costs, rebates make a real difference. Federal Small‑scale Technology Certificates (STCs) effectively act as a solar hot water rebate or heat pump hot water rebate at the point of sale, cutting the solar hot water price or heat pump hot water price by a substantial percentage. In WA, additional hot water rebate WA programs and occasional electric hot water system rebate offers can further reduce the upfront hot water system cost, particularly for replacing old gas hot water with an energy efficient hot water system. With typical savings of hundreds of dollars a year and payback periods shortened when you combine rebates with rooftop solar and smart timers or solar diversion, efficient hot water is becoming the best hot water system Australia‑wide for many regional homes.
If your existing unit is rusty, unreliable or you are weighing up electric hot water vs gas hot water, it is a good time to see whether your Dartnall home is ready for a hot water upgrade. Whether you are considering a chromagen solar hot water setup, rheem solar hot water repair, a rinnai solar hot water system or a quiet sanden heat pump, working with experienced local hot water WA specialists matters. With strong solar exposure and a community that is increasingly interested in sustainability, efficient hot water systems can cut your bills, lower emissions and future‑proof your home.
